Costa Luminosa scored full marks (100) in a recent inspection conducted by the Centers for Disease Control and Prevention (CDC) in the United States. 

The inspection was held on December 20 during a call at Miami, the homeport of the Costa Luminosa during winter 2014/2015. 

The CDC inspections are part of the Vessel Sanitation Program (VSP), which was introduced in the early 1970s and involves all ships that stop in a US port. They are unannounced events and are carried out by officials from the USPHS (United States Public Health Service) twice a year. The score, on a scale from 1 to 100, is assigned on the basis of a checklist with some 48 areas of assessment encompassing hygiene and sanitation of food (from storage to preparation), water, shipboard personnel and the ship as a whole.
